ll/llltlhlfi AND MEASURING MACHINE FOR CONCRETE.

SPEGIFEQA'MON forming part of Letters Patent No. 718,905, dated January20, 1903.

Application filed May '7, 1902. Serial No. 106,267. (No model.)

To to whom it may concern.-

Be it known that I, lVILLIAM H. BROWN, a citizen of the UnitedStates,residing at Elyria, in the county of Lorain and State of Ohio,have invented certain new and useful Improvements in Mixing andMeasuring Machines for Concrete; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it a ppertains to makeand use the same, reference being had to the accompanyingdrawings, andto the figures of reference marked thereon, which form a part of thisspecification.

This invention relates to mixing and measuring machines for concrete.

The object of the invention is to form a machine which will save timeand labor in measuring and mixing the different constituents ofconcrete.

Generally speaking, the machine comprises separate hoppers for cement,sand, and stone or otheringredientsandbelowthe hoppers cor respondingmeasuring and dumping wheels to take the material from the hoppers andto discharge the same into a trough. Means are provided to adjust thedischarge capacity of the wheels according to the proportions desired.

In the accompanying drawings, Figure 1 is a front elevation of themachine. Fig. 2 is a an end elevation thereof. Fig. 3 is a sectionaldetail of one of the wheels, showing the manner of changing the capacitythereof.

Referring specifically to the drawings, 6 indicates the frame of themachine, at the top of which is supported a series of hoppers 7, adaptedto respectively contain the several ingredients of the mixture. Beloweach hopper measuring and dumping wheels 8 are mounted to revolve on ashaft 0, journaled in hearings on the frame of the machine. Each ofthese wheels is divided by cross-partitions 8 into a number of pocketsto receive the material which drops from the hopper. The pockets havebottoms 9, which are retained by removable flanged irons 10, bolted tothe partitions. Said partitions have a series of holes 11, at any ofwhich the irons may be bolted, and corresponding bottoms being used thedepth and capacity of the pockets may be varied as desired.

An inclined chute or trough isindicated at 12, into which the pocketsempty.

13 indicates an apron in front of the Wheels to prevent the materialfrom falling out beyond the chute.

The revolving toothed cylinders or wheels 14: are levelers, revolving ina direction opposite to the sprocket-wheels 8 and serve to level off thesand and stone in the pockets. These levelers are illustrated as appliedonly to the sand and stone wheels, the cement-wheel being sufficientlyleveled by the lower edge of the hopper. The eifect of the levelers 14is to force back into the hopper any stone or sand in excess of thatsufficient to fill the pockets of the wheels.

The lower part of the back of the hoppers (indicated at 15) is hinged,as at 16, and is operated by screw and hand wheel 17, forming a gate toregulate the flow of material. The lower part of the front of the hopperis also hinged, as at 18, forming a door-19, which may be raised topermit access to the interior. Stops for the door are formed by buttons20, which project through a cross-bar 6* on the frame of the machine.

The rotating parts may be driven by any suitable gear.

It will be seen that by varying the capacity of the pockets theingredients of the mixture can be gaged to suit different requirements.As the material from the several wheels falls down the chute it becomesmixed and ready for the water.

What I claim is 1. In a machine of the class described, in combination,a series of hoppers, wheels having pockets of adjustablecapacity belowthe hoppers, adapted to receive material therefrom, rotating levelersover the pockets adjacent the mouth of the hoppers, and a mixing-chutebelow the wheels to receive the material falling therefrom.

2. In a machine of the class described, in combination, hoppers havinghinged gates at the bottom thereof to vary the flow of materialtherefrom, wheels below the hoppers havin g measuring-pockets receivingthe material 4. In a machine of the class described, in combination, thehoppers 7 the wheels 8 havin g measuring-pockets, the rotary leveiers14, the aprons 13, and the chute 12.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM H. BROWN.
